What is a terahertz in terms of frequency?

A terahertz (THz) is a frequency unit equal to 10^12 hertz, representing oscillations per second in the terahertz band.

How is wavelength in millimetres related to frequency?

Wavelength in millimetres is inversely related to frequency through the speed of light, expressed as wavelength = c / frequency under free-space conditions.

Where is converting THz to millimetre wavelengths commonly used?

This conversion is commonly applied in spectroscopy, wireless system design (like 5G mmWave), radar imaging, radio astronomy, and atmospheric remote sensing.
